摘要： In a vehicle headlight optical axis adjusting apparatus, inter-vehicle distance in each of divided zones is detected by a laser radar device. Desired optical axis raising angles for a vehicle headlight are calculated based on these inter-vehicle distances of the divided zones. The optical axis of the headlight is adjusted to the most downward pointing angle selected from among these angles, so that a driver of a preceding vehicle is not blinded.

摘要： A filter is changed to change a response in swivel adjustment of a direction of an optical axis of each swivel light based on a steering angle variation of a steering angle of a steering wheel measured with a steering angle sensor. The direction of the optical axis of each swivel light is adjusted based on a swivel control angle obtained upon application of the filter. A weaker filter is selected if the steering wheel is quickly steered, and a stronger filter is selected if the steering wheel is slowly steered. By this filtering operation, the direction of the optical axis of each swivel light is adjusted in response to the steering operation of the steering wheel without causing an uncomfortable feeling to a driver.

摘要： A pitch angle in the back-and-forth direction of the vehicle body is calculated based on output signals of height sensors disposed at front and rear wheels of the vehicle. A vehicle traveling speed is obtained. A vehicle acceleration is obtained from the vehicle traveling speed. Using the vehicle traveling speed and the vehicle acceleration, a judgement is made to determine the control mode corresponding to the vehicle traveling condition, by selecting one from the group consisting of a stopping mode, an acceleration mode, a deceleration mode and a constant-speed mode. An actuator target value (i.e., target aiming adjustment angle) is calculated in accordance with the determined control mode. To obtain this actuator target value, a filter is used to process the pitch angle so that the headlights do not dazzle an oncoming vehicle's driver. Then, the aiming adjustment for the headlights is performed by actuating actuators in accordance with the actuator target value. The pitch angle is adequately processed by using a preferable filter. Therefore, the aiming adjustment of the headlights is not performed unnecessarily or erroneously.

摘要： A height sensor has an exciting coil for generating an alternating magnetic field and a pickup coil for detecting the magnetic field. The exciting coil is fixed to a suspension arm and the pickup coil is fixed to a body so as to face each other. Distance between these coils is determined by a voltage outputted from the pickup coil, and a height of the vehicle is calculated from the distance between these coils by taking the mounting position of the pickup coil on the suspension arm into account. The height sensor is readily fixed and a detection accuracy is improved by setting the mounting position of the pickup coil in a range of {fraction (1/10)} to ½ of a length of the suspension arm from a connecting portion between the suspension arm and the body.

摘要： A lens body for providing a flat light distribution has a pair of reflective surfaces inclined vertically and symmetrically and used as an illuminating device for a vehicle which does not cause glaring against the on-coming vehicles traveling on the opposite lane. Light entering from an incident surface is emitted from an outgoing surface after being reflected. Areas illuminated by the pair of reflective surfaces are formed having a substantially horizontal cut line CL at the right and left sides of an illuminated area by direct light emitted from the outgoing surface directly without being reflected on the reflective surfaces.

摘要： In a vehicle headlight optical axis automatic adjusting system, a pitch angle in the longitudinal direction of a vehicle is calculated from a signal of a height sensor. Filtering corresponding to a control mode according to the acceleration is fixed and is not frequently switched unless the constant speed state of the vehicle continues for a predetermined time. The pitch angle may be calculated on the basis of the vehicle rear height value by using a prediction expression which is divided into a plurality of regions of vehicle postures according to loading conditions of an occupant load and a trunk load in correspondence with the vehicle type. The pitch angle may be updated when the vehicle enters a constant speed driving mode, i.e., stable driving mode, so that even when one trip is not finished the error is cancelled.

摘要： An automobile headlamp apparatus comprising a direct current driven discharge lamp surrounded by a concave main mirror which confronts a concave spheroidal sub mirror. The main mirror has a first focus point located substantially at a center of a discharge gap of the discharge lamp between the cathode and anode thereof, while the sub mirror has first and second focus points and an opening therein around the optical axis of the sub mirror. The first and second focus points of the sub mirror are arranged to be substantially on the tips of the cathode and anode of the discharge lamp, respectively. A convex lens may be included to condense the light from the main mirror, wherein the main mirror has a second focus point at a focus point of the convex lens. A shade forming a favorable illumination pattern may be included. In one embodiment, a diagonal mirror is inserted between the main mirror and the convex lens to bend the light from the discharge lamp. An optical light guide may be provided between the diagonal mirror and the convex lens, and/or the discharge tube may be attached to a completed assembly of the main mirror and sub-mirror.
